-------------------------------------
Summary: Delete Notification Events in Batches
Key: HIVE-24432
URL: https://issues.apache.org/jira/browse/HIVE-24432
Project: Hive
Issue Type: Improvement
Affects Versions: 3.2.0
Reporter: David Mollitor
Assignee: David Mollitor
Notification events are loaded in batches (reduces memory pressure on the HMS),
but all of the deletes happen under a single transactions and, when deleting
many records, can put a lot of pressure on the backend database.
Instead, delete events in batches (in different transactions) as well.
